That commit/fix was only a small part of all that has been reported in

I can not speak to specifics but there are a lot of potential reason's a

- They don't use the profile / or maybe apparmor. (package
maintainership evolves and not everyone who might even be aware of it
without digging in)

i have reenabled the capability rules ans added these to them, also from
the chromium profile:

.
i have prepared dbus rules:

what is ubuntu's policy for updating this profile? it looks like package
maintainers are not updating this profile on every package update. why?

i have some questions and wishes about rules that are in the profile:
# so browsing directories works
/ r,
/**/ r,
what if comment these out and allow / and owner @{HOME}/** , instead of
these? does firefox need other directory listings? maybe i will try.
i see /usr/ r, /etc/ r, /opt/ r,
i added these lines to ff profile:
#copied from abstractions/lightdm_chromium-browser
capability sys_admin, # for sandbox to change namespaces
capability sys_chroot, # fod sandbox to chroot to a safe directory
capability setgid, # for sandbox to drop privileges
capability
>At the moment we recommend granting the capability in the profile and
letting firefox setup its sandbox.
why do not ubuntu developers add it? (before they make it other way.)
>Unfortunately this means you can't guarantee the rest of the program
isn't doing things it shouldn't.
what it can do
I should further note that this needs kernel patches to be fixed.

Firefox uses cap sys_admin to set up its sandbox, which is extremely
unfortunate but required on linux to be able to set up the
user_namespace, do the chroot etc. Current the LSM and user namespaces
don't interact as well as they should.
AppArmor can NOT properly determine the policy namespace
i asked about sys_admin capability and got some answers:
